Materials and Methods: Observational and retrospective systematic review, which synthesizes the results of multiple primary investigations. These are an essential part of evidence-based nursing due to their rigorous methodology. In the final selection, 10 articles were chosen. We found that 20% (02) are from Spain, 20% (02) from Mexico, and 60% from Cuba (1), Portugal (1), the USA (1), Germany (1), Korea (1), Japan (1) respectively. Most of the studies are descriptive, with 40%, primarily from Spain and Mexico. Results: Identifying relevant studies, 90% of the 10 reviewed articles agree that if basic and adequate care is provided to the port catheter, complications are reduced by 90%. The search was restricted to articles with full text, and the selected articles were critically reviewed using the GRADE system to assign the strength of recommendations. Conclusions: The systematic review of the 10 articles aimed at nurses agrees in the majority that the essential care includes: correct asepsis, heparinization of the catheter port, use of the catheter between 7 and 15 days after placement, dressing changes every 7 days, and the port catheter prevents peripheral vascular injuries. The procedure must be performed by a trained professional in the field.

This study evaluated the concordance of Steiner, Ricketts, and the Element II of Andrews' Philosophy cephalometric analyses for determining the antero-posterior relationship of the upper maxilla in patients from the orthodontics second specialty clinic of the Universidad Norbert Wiener during the 2014-II to 2015-I period. It is an observational, prospective, cross-sectional study with a descriptive research level and a community or ecological design for multiple comparisons. Thirty cephalometric tracings were performed, which were evaluated by a single examiner. Each tracing underwent two cephalometric studies, and Element II of Andrews' philosophy was evaluated to determine the antero-posterior position of the upper maxilla. Results: The Steiner cephalometric analysis showed that 53% of patients had maxillary protrusion. The Ricketts cephalometric analysis showed that 57% of patients were within normal limits, and Element II of Andrews' philosophy showed that 60% of patients had maxillary retrusion. Using the Kappa statistical test, the study concluded that there was no concordance between the Steiner and Ricketts analyses (0.01946) for determining the antero-posterior position of the upper maxilla; nor was there concordance between the Element II of Andrews and Steiner cephalometric analysis (0.0865), or between Element II of Andrews and Ricketts cephalometric analysis (0.0948).

The objective of this study was to determine the inhibitory effect of the ethanolic extract of Bidens pilosa (Amor seco) compared to Colgate Plax® and 0.12% Chlorhexidine Gluconate against strains of Streptococcus mutans. The study was experimental, prospective, longitudinal, and analytical. The population consisted of Streptococcus mutans strains (ATCC 25175), and the sample consisted of 40 Petri dishes. The strains were reactivated and cultured on Blood Agar, where 6 mm diameter wells were made, and approximately 100 µl of the ethanolic extract of Bidens pilosa (Amor seco) were added in the following concentrations: 0.8/10, 1/10, and pure. The results were compared with 0.12% Chlorhexidine Gluconate as a positive control, distilled water as a negative control, and Colgate Plax® mouthwash. The results showed that the 0.8/10 and 1/10 concentrations of the ethanolic extract of Bidens pilosa (Amor seco) did not present any inhibition zone at any time. However, the pure ethanolic extract produced an average inhibition zone of 11.98 mm at 24 hours and 11.80 mm at 48 hours. Furthermore, a stronger inhibitory effect was observed with the positive control, 0.12% Chlorhexidine Gluconate, and a lesser inhibitory effect compared to Colgate Plax® mouthwash against the Streptococcus mutans (ATCC 25175) strain.

One hundred patients completed a questionnaire on their anxiety level before and after surgical intervention. One dental piece was extracted per patient, and the groups were divided based on the subvariable procedure complexity into the Impacted Teeth Group (n=50) and the Erupted Teeth Group (n=50). Based on the frequencies, data were gathered to form subvariables such as gender, dental arch (the area where the extraction was performed), and the frequency of previous surgical treatments. The anxiety level was assessed using the modified Corah scale. The data were transferred to the SPSS v22 statistical program. The U Mann Whitney test was used to compare the anxiety level based on procedure complexity, gender, and dental arch, while the Kruskal-Wallis test was used to compare it with the frequency of previous surgical treatments. A significance level of α<0.05 was considered.
